DPF regeneration function must only be disabled when there is a current danger caused by hot exhaust gasses such as parking on dry grass or other combustible materials. Excessive running of engine with function turned off will block the DPF filters.
Function does not reset after ignition off. It must be turned back on manually.
Amber warning on button means system has been deactivated.
